If you use the get json() method without any arguments, it will return None. See the Flask Request docs for further information: If the mimetype is JSON (application/json, see is json()), this will contain the parsed JSON data; otherwise, it will be None. You can know when someone has made a request.

Experts that work with the Python flask, HTML, and local JSON file say that you can use HTML to display JSON data from a local JSON file. With jsonify, the flask reads a local JSON file and sends it to index.html. Then, utilising that data, I'd like to provide the information.

JSON provided as a request with the application/json content-type is represented by json. You can also use the get json() method from the request object. Both the field and the method return a dict containing the key-value pairs found in the incoming JSON.

Use request.get json() to get JSON with the content type application/json in Flask. None is returned if the content type is incorrect. An error is raised if the data is not JSON.

To access the posted JSON data, simply use the request object's get json method, which parses the incoming JSON request data and provides it [2] as a Python dictionary. You can see the complete code below, which includes the start of the server by executing the run method on the app object.
